Abnormal weather events last year challenged growers, especially from a weed control standpoint. A herbicide expert shares how to gain control over weeds during the 2020 growing season.
Shawna Hubbard, trait herbicide product manager with Corteva Agriscience, says ?all technologies were put to the test” in 2019, including the Enlist weed control system.
?2019 put all technologies to the test,” Hubbard said. “But we did see great results in terms of broadleaf weed control with 2-4D choline, meeting and exceeding grower?s expectations around how the herbicide handles, behaves and stays on target.?
Hubbard recommends keeping detailed records and organizing multiple plans for best weed control results in the new year.
?Some things to keep in mind as we get ready for the next season (include) keeping a detailed field history, in terms of weed species and pressure. (We) had a lot of prevent plant acres out there and in some situations, weeds got too tall and contributed to the seed bank. Step number two (is) make a plan (and) thinking through how we best leverage our residual herbicide and then utilize options in our post-passes to control weeds.?
Producers are reminded: ?Multiple modes of action are key to keeping our technologies sustainable and weeds guessing.? Hubbard offers an easy way to apply multiple modes of action on your crop acres.
?One great benefit of the Enlist weed control system is you can tank mix Enlist One, which is 2, 4D choline with glufosinate herbicides,? Hubbard said. ?The ability to tank mix with the glufosinate is unique to the Enlist system, and gives us two truly effective modes of action, which is particularly helpful on tough waterhemp acres and other challenging weed species in the state of Iowa.?
